SLED.

SPECIFICATION forming part of Letters Patent No. 245,099, dated August 2, 1881.

' Application tiled March 7,1881. (No model.)

To all whom it may concern;

Be it known that I,'THOMAS S. TEW, a citizen of the United States, residing at Stanton, in the county of Montcalm and State of Michigan, have invented certain new and useful Improvements in Sleds; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Thisinvention relates to that class of sleds in which the bolster is connected by aloose joint to each runner; and it consists in the peculiar construction and arrangementof parts, as hereinafter more fully described, and then pointed out in the claims.

In the drawings, Figure 1 is a plan view; Fig. 2, aside view; Fig. 3, a cross-section; Fig. 4, a perspective view of the tongue-iron and front end of runner; Fig. 5, a detail view of roller, and Fig. 6 a cross-section of the same.

A represents the wooden runner, shod with iron in the usual manner, and provided with the ban g-iron B, the sole-plate b of which forms 7 a continuation of therunner-iron and turns over at the top, as shown at Fig. 4. This hang-iron is of L shape in cross-section,havin g a side plate, I), rising vertically from the plate b, through which passes the screw a, forming the pintle of the roller 0. Thisroller is formed of a light casting, having longitudinal strengtheningribs 0, and transverse ribs 0 extending from one cross-bar to the other, and forming a recess to receive the pole, which is secured therein by screws or bolts passing through both roller and pole. 7

At D is a standard, secured to the runner in any convenient manner, and provided with a recess,formin g, as shown in the drawings,about two-thirds of a circle; but I do not limit myself to this particular proportion,as anything over ahalf-circle will be sufliciently large. This recess receives the bolster-block E, which corresponds in shape to the recess in the standard, and is provided with a rib, e, fitting into 1 a groove, 41, in the standard, so as to prevent any sidewisp motion of the block in the standard, although allowing it to turn freely therein. K

The bolster-blocks have flanges 0 extending out on each side, and supported by brackets e, which flanges form a support for the bolsterF.

At t i may be seen flanges on the bolsterblock, which enter into grooves in the bolster, and serve the double purpose of strengthening the upper part of the bolster-block and to prevent the separation of the runners.

Attached to the roller 0 is a stay-bolt, G, passing through a flange of the standard, and secured therein by means of a nut, by which the stay-bolt can be tightened, as desired, to take off the strain from the pintle of the roller.

By the construction here shown a strong, yet cheap, sled is formedyand one which will readily yield to the inequalities of the road over which'it travels, as the runners move independently of each other, and yetthe flanges and grooves in the bolster, bolster-block, and standard prevent any separation of the parts when in vuse. If, however, it is desired to remove the bolster, it is only necessary to turn it on its side, as shown in dotted lines in Fig. 2,"when it canbe readily lifted out of the recess or as readily replaced when necessary.

By removing the bolster in the manner indicated and taking out the screws in the roller and removing the nuts on the stay-bolts, the wholesled may be taken to pieces.

What I claim as new is- 1. The combinationofabolster-block,formed partly circular in cross-section, with a runnerstandard provided with a recess fitting the curved portion of the bolster-block, the sides of the recess forming an incomplete circle whose center is within the recess, whereby the bolster-block and standard are held together when in normal position, but can readily be separated by tnrning the bolster-block, substantially as described.

2. The combination, with a sled-runner standard having a recess with curved walls and forming the major part of a circle, but open at top, of a bolster-block of corresponding shape, and adapted to turn therein, whereby the block is securely held in place when in working position, and yet capable of removal when turned at right angles, or nearly so, to its normal position, substantially as described.

,.3. The combination of the runner-standard D, provided with a recess forming the major part ofa circle, but open at the top, with the bolster-block E, shaped to fill said recess, and provided with a rib entering a groove in the recess, substantially as described, and for the purpose specified.

4. The combination of a pair of runners and the standards D, each provided with a recess forming the imjor part of a circle, with the bolster-block E, shaped to fill the recess, and provided with a rib entering a groove in said recess, and the bolster F, secured to the bolster-blocks, all constructed and stantially as shown and described.

5. The combination of a pair of runners, the bolster F, and the standards D, each standard being provided with a recess forming the major part of a circle, with the bolster-blocks E, shaped to fill the recess, and provided with arranged suban external rib enteringa groove in said recess, and internal ribs entering grooves in the b01- ster, all constructed and arranged substantially as shown and described.

6. The combination of the runners of a sled and the bang-irons B, provided with the sole 1) and side plate,b, with the roller 0, pivoted in said ban g-irons, substantially as described.

7. A sled-roller consisting of the open casting 0, having the ribs 0 and transverse ribs 0, substantially as and for the purpose specified.

In testimony whereof I atfix my signature in presence of two witnesses.

THOMAS S. TEW.
